cc3200 launchpad dead on arrival?

Other Parts Discussed in Thread: CC3200, UNIFLASH

We've just just purchased a cc3200 launchpad from the TI web shop.

When it arrived, I installed the newest Code Composer, service packs, uniflash, flashed it, followed the start guides and so on. It seemed to work. Sort of. (There were some unexplained quirks here and there)

I wasn't able to make it connect to our WiFi WPA2 AP though. And it wasn't able to scan either. So I decided to set up an OPEN AP, placed on my desk, right next to the launchpad. Just to see it working. 

Two day later I've set up the AP. (Distance: 1 m) But now I'm not able to run the sample code in Code Composer. 

I'm able to compile, start up the debugger, step through the code, the LEDs are working, but whenever I get to a "sl_Start", the debugger fails with the following msg:

"Cortex_M4_0: Error: Connection with the target was unexpectedly lost."

I've tried several of the included projects. Same error. I've verified the jumpers. I've rebuild the projects, repowered everything, changing usb slot and so on.

I'm guessing that the unit is faulty and has been so on arrival? (Please correct me if I'm wrong.)

How and where do I contact TI, to send me a replacement?

    Hi Morten,

         When your CC3200 Launchpad arrived, did you try the Out of Box Demo using your smartphone?

    Yup, start guides told me to do so. 

    And it mostly worked. (It had trouble storing the things I entered and it couldn't connect to an AP.)

    It seems that I've solved the jtag issue:

    "Cortex_M4_0: Error: Connection with the target was unexpectedly lost."

    I replaced the usb cable.

     

    However, I'm still not able to connect to an AP. Neither the WPA2 or the OPEN one.

    Out of Box Demo is not mentioned at CC3200 Launchpad Getting Started Guide. 

    I am referring to this below.

    So, did you follow the CC3200 Getting Started Guide? What sample code did you try that you encounter this error message below?

    "Cortex_M4_0: Error: Connection with the target was unexpectedly lost."

    Also, are you sure that your Access Point is WPA2?

    Well, I did try out the Out of Box Demo. (The one from the video.) And I can connect to the unit with my smartphone.

    But I cannot make the unit connect to any Access Points. I have 1 that are WPA2 and one OPEN. It won't connect to any of them. And when it scans, it cannot see the WPA2 one. Even though it got plenty of signal. (It can see some other APs with much less signal)

    Hi Morten,

    What code examples did you run specifically to try and connect to WPA2 AP? Did you go through the Smartconfig process using the Out Of Box? What are you using as the indicator of whether its connected to the AP or not?

    Regards,

    Aaron

    I've tried to connect to an OPEN AP and a WPA2 AP, through the OOB, through the SmartConfig and through the wlan_station.

    I prefer the wlan_station sample due to simplicity.

    The sample never gets over the "WlanConnect" function. (It never connects.)

    Here's the console output:

    ===================================================================


    *************************************************
    CC3200 WLAN STATION Application
    *************************************************

    Host Driver Version: 1.0.0.1
    Build Version 2.2.0.1.31.1.2.0.2.1.0.3.23
    Device is configured in default state
    Device started as STATION

    ===================================================================

    Edit: It gets stuck in the loop where the red LED is blinking. My phone is able to connect to both APs. 

    I've also tried several of the other samples. But most of them are fairly useless, when it can't connect to an AP.

    Sometimes I get the this output: (But not always.)

    ===================================================================

    [WLAN EVENT] STA Connected to the AP: PCH-WL ,BSSID: c8:d7:19:39:dc:4b

    ===================================================================

     

    The "PCH-WL" is the WPA2 AP. The above is still not enough to make it "connect" though.

    Wait, I've made it connect to WPA2 AP. (I restarted the company router.)

    I still can't connect it to the OPEN AP, but I guess that 1 connection is good enough for now.

    Thank you.

    Have you since learned anything about your problem? I'm having the same issue. Stops at "Device started as STATION"
